Interesting, isn't it? Caterpillars pretending to be something else. Here's one, a very poisonous caterpillar, the puss caterpillar, pretending to be President Trump's toupee (Megalopyge opercularis):

President Trump' toupee:

And here is a little bird nestling that pretends to be a poisonous caterpillar, the very same President Trump's toupee caterpillar, a Laniocera hypopyrra nestling:Laniocera hypopyrra nestling development in lowland Amazonian forest in southeastern Peru. a, Day 1, nestling with long orange
barbs with white tips. b, Day 4, nestling in nest next to unhatched egg. c, Day 9, nestling feathers have started to emerge and eyes have
started to open. d, Day 14, most of the body feathers have completely emerged, eyes are completely open, and wing feathers are emerging.
e, Day 18, all body feathers have completely emerged, and the wing feathers are ~90% emerged. f, Caterpillar (Megalopygidae) in the area
that matches the nestling’s plumage characteristics.

I guess I'm far enough along to let the cat out of the bag and share a couple WIP renders of my "secret" project. I'm still working on the textures and adding in more species/morphs
Yes, Janet, one of your guesses was right

The default species for the base set...young Red-eared Sliders. I still need to add the displacement to the shell on this. The slider will be the only species in the base set but will have adult, youngster and old textures (the species dulls and darkens with age).

and the Desert Tortoise from "Volume I: Tortoises of the World". Other species will include the Russian tortoise, Yellow-footed tortoise, Leopard Tortoise, Common tortoise, Hermann's tortoise and Kleinmann's tortoise. ...and yes, the tortoise is in my Sagebrush Habitat and Habitat Extender which is pretty much their natural habitat. I will probably be adding an additional plant set with White Sage (Salvia apiana) and Desert Mallow (Sphaeralcea ambigua). The mallow is a favorite food of desert tortoises.

That's so awesome! My neighbor son's had a tortoise and she watched it over the winter once while it was hibernating. It slept in a box under her bed. Once it woke up I saw it eating strawberries and it's cheeks would turn red! I can't wait to make this guy walk!
